Dentists need to know the science has changed

Advert aired on New Zealand television in 2014. Whangarei dentist Dr Lawrie Brett explains that dentists used to be taught that children needed to swallow fluoride to strengthen enamel as teeth were growing but no the science has changed so the effectiveness of fluoride needs to be questioned.

The NZ School Dental Statistics are the most robust set of data we have on dental health in New Zealand. The Ministry of Health have now published the 2015 data which show no difference in decay rates between fluoridated and non-fluoridated areas.
